After installing the prolific driver I downloaded from http://www.wiretek.com.cn/download.asp?driver_lei=windows (named USB2.0 TO RS232 Converter), I plugged in the device and got the error USB Device Not Recognized (one of the USB devices attached to this computer has malfunctioned…)

I opened device manager and the device shows up as “Unknown Device” under the USB controller tab.

I got the same error on all two computers at my house (all running windows xp pro).but one computer has running correct!!!

Has anyone else had the same error, or is my device defective? Help would be appreciated.

Thanks

The driver depends on the USB converter you are using. Rabbit recommends and sells converters based on the FTDI FT232R chip. This chip is used both in our USB to RS-232 cable and in the new USB programming adapter. The newer versions of DC automatically install the FTDI driver, but if you’re using one of Rabbit’s adapters and are having difficulty, you can download the latest driver from FTDI here:

USB adapters not using the FTDI chip may or may not work with DC. The only adapters we guarantee support for are based on the FTDI chip.
